Catch 'em all someplace else. That's the message from the United States Holocaust Museum in Washington, D.C., that has urged its visitors to stop playing Pokemon Go there.

Built in remembrance of the millions of Jews who died at the hands of the Nazis before and during World War II, the D.C. tourist destination is now also a so-called "Pokestop," where players of the instant hit smartphone game can get free power-ups to aid in their hunt for more fantastical creatures.

We welcome & encourage visitors to use technology to engage w/our exhibitions & programs while being respectful of our role as a memorial.

"Playing the game is not appropriate in the museum, which is a memorial to the victims of Nazism," Andrew Hollinger, the facility's communications director, told The Washington Post. "We are trying to find out if we can get the museum excluded from the game."

The museum reiterated the sentiment in a tweet.

"We welcome & encourage visitors to use technology to engage w/our exhibitions & programs while being respectful of our role as a memorial," the tweet read.

@NianticLabs Do not allow playing 'Pokémon Go' on the site of our Memorial and similar places. It's disrespectful to the memory of victims!
